Dr. Divya Sharma is an assistant professor at A Biodiction. The document discusses the process of creating recombinant plasmids by inserting a gene or DNA fragment of interest into a circular piece of DNA called a plasmid using restriction enzymes and ligase. This recombinant DNA can then be used to create transgenic plants by modifying tumor-inducing genes (Ti-plasmids) that lack transferable genes and inserting the gene of interest instead. The document then discusses various types of Agrobacterium strains used, the regeneration and selection process for transgenic plants, and methods for detecting and characterizing the inserted trait genes. Some examples of commercial transgenic crops are also provided, such as golden rice engineered for vitamin A production and herb
This document summarizes methods for using inorganic nanoparticles to probe DNA structure. CdS quantum dots are synthesized through reactions with cadmium nitrate and sodium sulfide. The nanoparticles are then "activated" through addition of cadmium ions, which coats them in a loose web of cadmium. Oligonucleotides of interest are purified by HPLC and annealed to form DNA structures. Titrations of the activated quantum dots with different DNA structures allow inference of local DNA dynamics based on changes in nanoparticle fluorescence.
The document discusses plant protoplast isolation, purification, and culturing. Some key points:
- Protoplasts are plant cells that have had their cell walls removed, leaving just the plasma membrane. They allow for plant cell fusion and regeneration.
- Protoplasts are typically isolated from plant tissues like leaves using enzymatic digestion with cellulase and pectinase. This yields more protoplasts than mechanical methods.
- Isolated protoplasts are purified by centrifugation and washing to remove cell debris. They are then cultured in liquid or solid nutrient media and tested for viability before regeneration.

1. Callus culture involves growing undifferentiated plant cells and tissues on a nutrient medium under sterile conditions. This allows for the production of genetically identical clones without seeds or pollination.
2. A callus is an unorganized mass of cells formed from injured or cultured plant tissue. Successful callus culture requires selecting an explant, preparing sterile culture media, and regulating hormone levels to induce cell proliferation.
3. Callus cultures are maintained through periodic sub-culturing to replenish nutrients and prevent toxicity. The growth and characteristics of callus tissue can provide insights into plant cell metabolism, differentiation, and pathways for genetic engineering applications.
The document discusses organogenesis, which is the development of adventitious organs or primordial from undifferentiated plant cell mass through differentiation. It describes the process, including dedifferentiation and redifferentiation stages. There are two types of organogenesis - direct organogenesis which does not involve callus formation, and indirect organogenesis which involves callus formation. Organogenesis is used in plant tissue culture to regenerate plants through shoot or root cultures and is influenced by factors like explant source and size, plant growth regulators, and culture conditions. It has commercial applications in micropropagation of plants.
1. Somatic embryogenesis is a process where embryos are formed from somatic plant cells, such as leaf cells, that are not normally involved in embryo formation. 2. These somatic embryos develop through similar stages as zygotic embryos, including globular, heart-shaped, torpedo-shaped, and cotyledonary stages. 3. Somatic embryogenesis can occur through direct embryogenesis from explant tissue or indirect embryogenesis which involves first forming a callus that then develops embryos.

Micropropagation is a tissue culture technique used for the rapid asexual propagation of plants. It involves culturing small pieces of plant tissues or organs on growth media in controlled conditions. The process includes initiation of cultures from explants, multiplication through shoot proliferation or somatic embryogenesis, rooting of shoots, and transplantation of plantlets to soil. Micropropagation allows for large-scale production of genetically identical clones in a short period of time. It has applications in producing disease-free plants, conserving rare species, and commercializing new plant varieties.
This document summarizes the culture of in-vitro pollination and fertilization. It describes the different types of in-vitro pollination including ovular, ovarian, placental and stigmatic pollination. The methods of in-vitro pollination and fertilization are outlined involving sterilization procedures and suitable media and explants. Applications include using in-vitro fertilization to overcome self-incompatibility in some plants or enable intergeneric crosses. The techniques used involve isolating pollen and egg cells, inducing fusion through electrofusion, and culturing the fertilized eggs on nutrient media to develop into plants. Considerations for successful in-vitro fertilization include the physiological state of
Dr. Divya Sharma discusses plant growth regulators and their roles in plant growth and development. There are internal and external factors that influence plant growth. Hormones called phytohormones regulate many processes including flowering, stem and leaf formation, fruit ripening, and more. The major classes of plant growth regulators are auxins, cytokinins, gibberellins, ethylene, and abscisic acid. Auxins promote cell elongation and root formation while cytokinins stimulate cell division and shoot growth. Gibberellins promote stem elongation and flowering. Together these hormones precisely control plant growth and differentiation.

ESR spectroscopy in liquid food and beverages.pptxPRIYANKA PATEL
With increasing population, people need to rely on packaged food stuffs. Packaging of food materials requires the preservation of food. There are various methods for the treatment of food to preserve them and irradiation treatment of food is one of them. It is the most common and the most harmless method for the food preservation as it does not alter the necessary micronutrients of food materials. Although irradiated food doesn’t cause any harm to the human health but still the quality assessment of food is required to provide consumers with necessary information about the food. ESR spectroscopy is the most sophisticated way to investigate the quality of the food and the free radicals induced during the processing of the food. ESR spin trapping technique is useful for the detection of highly unstable radicals in the food. The antioxidant capability of liquid food and beverages in mainly performed by spin trapping technique.

Unlocking the mysteries of reproduction: Exploring fecundity and gonadosomati...AbdullaAlAsif1
The pygmy halfbeak Dermogenys colletei, is known for its viviparous nature, this presents an intriguing case of relatively low fecundity, raising questions about potential compensatory reproductive strategies employed by this species. Our study delves into the examination of fecundity and the Gonadosomatic Index (GSI) in the Pygmy Halfbeak, D. colletei (Meisner, 2001), an intriguing viviparous fish indigenous to Sarawak, Borneo. We hypothesize that the Pygmy halfbeak, D. colletei, may exhibit unique reproductive adaptations to offset its low fecundity, thus enhancing its survival and fitness. To address this, we conducted a comprehensive study utilizing 28 mature female specimens of D. colletei, carefully measuring fecundity and GSI to shed light on the reproductive adaptations of this species. Our findings reveal that D. colletei indeed exhibits low fecundity, with a mean of 16.76 ± 2.01, and a mean GSI of 12.83 ± 1.27, providing crucial insights into the reproductive mechanisms at play in this species. These results underscore the existence of unique reproductive strategies in D. colletei, enabling its adaptation and persistence in Borneo's diverse aquatic ecosystems, and call for further ecological research to elucidate these mechanisms. This study lends to a better understanding of viviparous fish in Borneo and contributes to the broader field of aquatic ecology, enhancing our knowledge of species adaptations to unique ecological challenges.
EWOCS-I: The catalog of X-ray sources in Westerlund 1 from the Extended Weste...Sérgio Sacani
Context. With a mass exceeding several 104 M⊙ and a rich and dense population of massive stars, supermassive young star clusters
represent the most massive star-forming environment that is dominated by the feedback from massive stars and gravitational interactions
among stars.
Aims. In this paper we present the Extended Westerlund 1 and 2 Open Clusters Survey (EWOCS) project, which aims to investigate
the influence of the starburst environment on the formation of stars and planets, and on the evolution of both low and high mass stars.
The primary targets of this project are Westerlund 1 and 2, the closest supermassive star clusters to the Sun.
Methods. The project is based primarily on recent observations conducted with the Chandra and JWST observatories. Specifically,
the Chandra survey of Westerlund 1 consists of 36 new ACIS-I observations, nearly co-pointed, for a total exposure time of 1 Msec.
Additionally, we included 8 archival Chandra/ACIS-S observations. This paper presents the resulting catalog of X-ray sources within
and around Westerlund 1. Sources were detected by combining various existing methods, and photon extraction and source validation
were carried out using the ACIS-Extract software.
Results. The EWOCS X-ray catalog comprises 5963 validated sources out of the 9420 initially provided to ACIS-Extract, reaching a
photon flux threshold of approximately 2 × 10−8 photons cm−2
s
−1
. The X-ray sources exhibit a highly concentrated spatial distribution,
with 1075 sources located within the central 1 arcmin. We have successfully detected X-ray emissions from 126 out of the 166 known
massive stars of the cluster, and we have collected over 71 000 photons from the magnetar CXO J164710.20-455217.
The debris of the ‘last major merger’ is dynamically youngSérgio Sacani
The Milky Way’s (MW) inner stellar halo contains an [Fe/H]-rich component with highly eccentric orbits, often referred to as the
‘last major merger.’ Hypotheses for the origin of this component include Gaia-Sausage/Enceladus (GSE), where the progenitor
collided with the MW proto-disc 8–11 Gyr ago, and the Virgo Radial Merger (VRM), where the progenitor collided with the
MW disc within the last 3 Gyr. These two scenarios make different predictions about observable structure in local phase space,
because the morphology of debris depends on how long it has had to phase mix. The recently identified phase-space folds in Gaia
DR3 have positive caustic velocities, making them fundamentally different than the phase-mixed chevrons found in simulations
at late times. Roughly 20 per cent of the stars in the prograde local stellar halo are associated with the observed caustics. Based
on a simple phase-mixing model, the observed number of caustics are consistent with a merger that occurred 1–2 Gyr ago.
We also compare the observed phase-space distribution to FIRE-2 Latte simulations of GSE-like mergers, using a quantitative
measurement of phase mixing (2D causticality). The observed local phase-space distribution best matches the simulated data
1–2 Gyr after collision, and certainly not later than 3 Gyr. This is further evidence that the progenitor of the ‘last major merger’
did not collide with the MW proto-disc at early times, as is thought for the GSE, but instead collided with the MW disc within
the last few Gyr, consistent with the body of work surrounding the VRM.
ESPP presentation to EU Waste Water Network, 4th June 2024 “EU policies driving nutrient removal and recycling
and the revised UWWTD (Urban Waste Water Treatment Directive)”
The ability to recreate computational results with minimal effort and actionable metrics provides a solid foundation for scientific research and software development. When people can replicate an analysis at the touch of a button using open-source software, open data, and methods to assess and compare proposals, it significantly eases verification of results, engagement with a diverse range of contributors, and progress. However, we have yet to fully achieve this; there are still many sociotechnical frictions.
Inspired by David Donoho's vision, this talk aims to revisit the three crucial pillars of frictionless reproducibility (data sharing, code sharing, and competitive challenges) with the perspective of deep software variability.
Our observation is that multiple layers — hardware, operating systems, third-party libraries, software versions, input data, compile-time options, and parameters — are subject to variability that exacerbates frictions but is also essential for achieving robust, generalizable results and fostering innovation. I will first review the literature, providing evidence of how the complex variability interactions across these layers affect qualitative and quantitative software properties, thereby complicating the reproduction and replication of scientific studies in various fields.
I will then present some software engineering and AI techniques that can support the strategic exploration of variability spaces. These include the use of abstractions and models (e.g., feature models), sampling strategies (e.g., uniform, random), cost-effective measurements (e.g., incremental build of software configurations), and dimensionality reduction methods (e.g., transfer learning, feature selection, software debloating).
I will finally argue that deep variability is both the problem and solution of frictionless reproducibility, calling the software science community to develop new methods and tools to manage variability and foster reproducibility in software systems.

Phenomics assisted breeding in crop improvementIshaGoswami9
As the population is increasing and will reach about 9 billion upto 2050. Also due to climate change, it is difficult to meet the food requirement of such a large population. Facing the challenges presented by resource shortages, climate
change, and increasing global population, crop yield and quality need to be improved in a sustainable way over the coming decades. Genetic improvement by breeding is the best way to increase crop productivity. With the rapid progression of functional
genomics, an increasing number of crop genomes have been sequenced and dozens of genes influencing key agronomic traits have been identified. However, current genome sequence information has not been adequately exploited for understanding
the complex characteristics of multiple gene, owing to a lack of crop phenotypic data. Efficient, automatic, and accurate technologies and platforms that can capture phenotypic data that can
be linked to genomics information for crop improvement at all growth stages have become as important as genotyping. Thus,
high-throughput phenotyping has become the major bottleneck restricting crop breeding. Plant phenomics has been defined as the high-throughput, accurate acquisition and analysis of multi-dimensional phenotypes
during crop growing stages at the organism level, including the cell, tissue, organ, individual plant, plot, and field levels. With the rapid development of novel sensors, imaging technology,
and analysis methods, numerous infrastructure platforms have been developed for phenotyping.
